IMPROVEMENT IN UMBRELLAS.

Specification forming part of Letters Patent No. 141,941', dated August19, 1873 application filed March 8, 1873.

To all whom t may concern:

Beit known Athat I, JOHN MOAULIFFE, of the city, county, and State ofNew York, have invented a new and Improved Lap 7 for Gonnecting UmbrellaRibs and Braces, of which the following is a specification:

I propose to make clips or laps for fastenin g to umbrellaribs, to pivotthe braces to, by taking little strips of sheet metal, well coated withtin, and fold the ends over back on one side, say, about twice, 4orenough to make the elevation of the folded part about half the thicknessof the rib, and so that the space between the said folded part will bejust enough to wrap around the brace and inclose it snugly when thefolded parts meet on the inside of the rib, to form a projection towhich the branched end of the brace can be pivoted; and these ends andthe folds I unite together, and also unite the lap to the rib, by a dropof solder from the soldering-iron, and by heating the lap so as to fusethe solder on it, and thus have a strong lap securely fastened to therib without too much solder, and without indenting the rib, whichweakens it and renders it liable to break.

Figure l is a side elevation of part of an umbrella-rib, also part of abrace, and also my improved lap fastened to the rib, and the bracepivoted to it. Fig. 2 is an end elevation of Fig. 1. Fig. 3 is a diagramof lthe sheet-metal blank I use for the lap. Fig. 4 is a plan view of itwith the ends folded up ready for wrapping around the brace. Fig. 5 isan end elevation of Fig. 4; and Fig. 6 is an end elevation of the lap,showing the form after it is wrapped around the rib.

.Similar letters of reference indicate corresponding parts.

A is the umbrellarib; B, the brace; C, the lap.

To make this lap, I take a thin strip of tinned sheet metal, of approvedwidth, and of the length required, which I previously ascertain, andfold the ends on one side, say, two folds, as shown at D, Figs. 4 and 5,making the folds as long as I wish the lap to project from the rib, andtaking care that the space E between the folds will be just long enoughto wrap around the rib and inclose it snugly in the space F, Fig. 6, andthen apply a drop or two of solder by the hot soldering-tool, and heatthe folded lap so as to fuse the tin on it to unite all the folds, andunite the whole to the rib and fill up any spaces that may be betweenthe ends of the folds and the rib. Before wrapping the lap around therib I will polish the latter clean, so that the solder will readilyunite with it.

Thus I make a simpler, cheaper, and better lap than any heretofore made.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination, with ribs A, of the sheet-v lnetalstrip, having a doublelap, D, at each end, and an intermediate space, E,which entirely closes said rib, as shown and described.
